MINER, INC., OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE CAR CONSTRUCTION Application filed January 24, 1929. Serial No. 334,691.

This invention relates to improvements in car construction.

One object of the invention is to provide means for connecting the body and truck bolsters of a railway car to prevent separation of the bolsters, especially in the event of collision, and thereby eliminate the danger of telescoping of cars, the connecting means be mg in the form of a multlpart center pin, certain members of which have shouldered engagement with the bolsters, the last named members of the pin being collapsible to permit assembling thereof by insertion through the center pin receiving openings, the parts 5 being held in expanded condition by a filler member or spreader to maintain the shouldered engagement between the pin and the bolsters, the assembled members of the pin together forming a retaining element of exceptionally large cros sectional area at the cooperating center bearing portions of the two bolsters to effectively resist shearing action. A more specific object of the invention is to provide a center pin construction for connecting the body and truck bolsters of railway cars, including two outer members together forming a tubular connecting element, and a central filler member, the latter holding the outer members of the pin expanded, the two outer members each being headed at opposite ends and having shouldered engagement with both bolsters, said outer members at one end portion of the pin having contact with each other along their inner sides when assembled with the bolsters, and being cut away on their inner sides at the other end portion of the pin to allow contraction of the head portions at said end to permit insertion through the center pin openings of the bolsters.

A still further object of the invention is to provide a center pin connection for the body and truck bolsters of railway cars, wherein the pin is of the character hereinbefore indicated, is relatively short and has shouldered engagement with both bolsters at closely adjacent points, thereby providing a rugged locking element which may be readily assembled with the bolsters.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawing, forming a part of this specification, Figure 1 is a top plan view of a portion of the body bolster of a railway car, illustrating my improvements in connection therewith. I Figure 2 is a vertical sectional view through the body and truck bolsters of a car, corresponding substantially to the line 22 of Figure 1. And Figure 3 is a horizontal sectional view, partly broken away, corresponding substantially to the line 3-3 of Figure 2.

In said drawing, 10 indicates generally the body bolster of a railway car and 11 a portion of the co-operating truck bolster. The body bolster 10 is provided with the usual top and bottom web portions connected by a cylindrical sleeve section 12 which accommodates the center pin. The bottom web of the bolster is provided with the usual bearing projection 13 which is formed integral with the sleeve 12 and has a spherical bottom bearing surface 14 which cooperates with a spherical bearing surface 15 formed on a bearing block 16 seated in a pocket 17 provided at the top of the truck bolster 11.

As most clearly shown in Figure 2, the bearing block 16 is provided with an upstanding annular flange 18 which extends into a pocket or opening 19 formed at the bottom of the body bolster. The truck bolster is also provided with the usual top and bottom web portions connected by vertical transverse spaced walls 50 defining a pocket 23 adapted to accommodate the bottom head of the center pin.

In carrying out my invention, I provide the body and truck bolsters with alined center pin receiving openings 21 and 22. The opening 22 of the truck bolster extends through the bearing block 16. As most clearly shown in Fig ure 2, the pocket 23 is of greater width than the diameter of the opening 22 and serves to accommodate the head portion at the lower end of the center pin or retaining element, as hereinbefore pointed out, which is employed to connect the two bolsters. An annular shoulder 24 is thus provided at the junction of the pocket 23 and the opening 22. The

.major portion of the sleeve section 12 of the body bolster is of larger diameter than the opening 21, thereby providing a pocket 25, and an annular shoulder 26 at the bottom of said pocket adjacent the pin receiving opening 21.

My improved center pin proper comprises a pair of counterpart outer sections AA and a central filler or spreading member B. The sections A of the pin are of identical construction,"a'ndthe two sections when assembled,

flange 28 at the upper endthereof, adapted to cooperate with the shoulder 26 of the body A bolster, the flanges 28 of the two sections A together forming an annular head member at the upper end of the pin. The portions of the vmembers A, between the top and bottom flanges thereof, form the shank of the center pin. The shank portion is of substantially cylindrical shape in horizontal cross section and fits within the center pin openings 21 and 22 of the two bolsters when the spreading or filler element B is assembled therewith.

The filler member B is in the form of a substantially cylindrical bar or rod and is adapted to fit snugly within the sections A, each of the sections being provided with a seat 29 adapted to accommodate the corresponding side of the member B, the two seats '29 together forming a vertical bore at the center of the pin, of cylindrical horizontal cross section, The bottom end of the member B is tapered, as indicated at 30, to facilitate insertion of said member between the sections A of the pin. At the upper end, the member B is provided with a head 31 adapted to seat 011 top of the pin to hold the member B against downward movement and prevent accidental displacement of the same, The head 31 may also be provided with an eye member 32, as shown, with which a tool may be engaged .to facilitate removal of the filler member B. p I

As shown in Figure 2 of the drawings, the

flanges 28 at the upper ends of the sections A have the edge faces cut away, as indicated at 33, to provide in eflect an upwardly tapered head member. By thus cutting away the flanges, the sections A may be rocked inwardly on each other in assembling the same with the bolsters, without actual contact between the flanges and the side walls of the pocket 25. Immediately below the flange portions 28, the sections A are cut away, as indicated at 34, to provide in effect an annular groove which will clear the shoulder 26 at '35, thereby permitting inward rocking movement of the bottom portions of the sections A toward each other to eflect contraction of the lowerend of the pin when the filler member is not in position so as to per- .mit insertion of the flange portions 2T2T through the center pin receiving openings 21 and22 of thetwobolsters. The openlngs 21 and 22 preferably have diametrically opposite side wall portions thereof cut away as 5 indicated at 40 40 whereby the flange members 2727 maybe made of relatively great width to overlap the annular shoulder 24 to maximum extent, the cut away portion 40 240 defining vertical guideways to accommodateithe inner ends of the flanges at diametrically opposite-sidesof the pin.

' In assembling my improved center pin with .the' bolsters of a railway car, the sections'A are insertedns a unit through the pocket of the body bolster, with'the inner edge portions 35 thereof in contact. The head section *formed by the flanges 27 is thus contracted to an extent that the same will pass freely through the .pin receiving openings 21 and 22 and guideways 40f'40.

The two sections A are passed downwardly through the pin'receiving openings 21 and 22 until the flanges '27 are disposed within the pocket 23 of the truck bolster beneath the annular shoulder 24. As will be evident, when the sections A of the pin are being assembled with the bolsters in the manner pointed out, the upper'end portions of said sections will be spread apart slightly, thereby tilting the head portions formed by the flanges 28. Clearance for passage of the parts through the pocket 25 and the opening 21 past the shoulder 26 while the parts are thus tilted, is provided by cutting away the flanges 28 and the shankportions of the members A adjacent said flanges, as hereinbefore pointed out.

After the sections A have been assembled with the bolsters in the manner j ust'described,

the filler or spreading member B is inserted between the sections through the pocket 25 of the body bolster. The insertion of the member B between the sections A is facilitated by the tapered bottom end portion of said memrelation with the annular shoulder 24. Then llU the filler member B has been fully inserted, the inner edge'portions of the sections A at the upper portion of the pin will be in fiatfaced engagement, as shown in Figure 2. As hereinbefore pointed out, the head member 31 of the filler B limits the downward movement thereof by engagement with the upper end portions of sections A.

As will be evident, when the parts have been completely assembled, the two members A and the filler member B together form a substantially solid pin, the shank of which fills the center pin receiving openings 21 and 2.2 of the bolsters.

Considerable strength against shearing is provided in my improved center pin construction by bringing the inner edges of the sections A, at the upper end of the pin, into bearing contact. As the contacting ortions of the sections A extend a considera le distance below the upper end of the pin to a point adjacent the bearing connection between the two bolsters, the pin presents a cross sectional area at that point substantially the same as the cross sectional area of the pin receiving opening, thereby providing the maximum resistance against shearing.

Although my improved pin has been described andshownasbeingassembled with the bolsters by passing all the members thereof through the pocket of the body bolster into the pin receiving openings, it will be evident that the outer sections A may be assembled with the bolsters by reversing the same, end for end, and inserting the same through the pocket 23 of the truck bolster, the flanges 27 being disposed uppermost and in contracted relation. After the members or sections A have been thus assembled, the filler member may be inserted between the same, either through the opening of the body or the opening of the truck bolster. It is also possible to apply the filler member B through the opening of the truck bolster, with the sections A assembled, as shown in Figure 2.

WV hen the filler member B is applied from the bottom, it is evident that some means must be provided to prevent removal of the same in a downward direction. Any well known retaining means may be employed for this purpose.

lVhen it is desired to separate the body and truck bolsters of a car, it is merely necessary modifications that come within the scope of claims appended hereto.
